Color Contrast Ratio

Color Contrast Ratio is a number that shows how different two colors are from each other, which helps people see and read things better. For designers, a higher color contrast ratio between text and background makes words easier to see for everyone, including people who may have trouble seeing colors. A simple way to check this is by using black and white as a reference, which gives the highest difference. Designers can use color contrast ratio to choose colors that work well together, making sure that information is clear and easy to spot. This helps everyone enjoy and use designs, no matter how well they see colors.

visual clarity, readable text, user interface design, legibility, color accessibility, inclusive design
